Zaiband and V both handle this by using a parameter to signal whether occupied squares block (bolt/physical missile) or not (ball, beam).

In V:
* o blocks @'s shot of p but does not block p's shot of @
* y blocks p's shot of @ but does not block @'s shot of p

DFOV indeed would not let either o or y provide cover for anyone. The gameplay effects of this are indeed pervasive.
